Description
A pasture production model was modified to account for the effect of tree water use on pasture production in woodlands of norJhern Australia. Simulation experiments with the model indicate that competition for water explains the effect of trees on pasture production. Trees compete for water most strongly (I) in shallow soils; (2) when tree roots are shallow; and (3) when intra-seasonal dry periods reduce the amount of water available for transpiration.
